King, Loveland, Ohio, assignor to The Steelcraft Manufacturing Company, Rossmoyne, Ohio, a corporation of Ohio Filed May Z, 1966, Ser. No. 547,046 4 Claims. (Cl. 160-90) ABSTRACT OF THE DISCLOSURE The disclosure relates to a convertible screen and storm door for installation in an outside wall of a building, including a 'slidable storm window panel and a xed .screen sash having a frame. The door proper is formed of sheet metal, comprising hollow vertical stiles and horizontal cross members, the upper portion of the door having an opening delineated by the vertical stiles and the upper horizontal cross member. The lower portion of the door constitutes a closure panel extending downwardly between the stiles from the lower portion of the opening to the lower cross member, the panel also being of hollow sheet metal construction.

The closure panel, at one side or the door, includes an inset area which forms a storage well for the storm window panel when it is lowered. The stiles include opposed inner walls having channel-shaped guide channels with the open sides of the channels facing one another, and with the marginal side edge portions of the storm window panel confined in the guide channels and adapted to be shifted selectively to an elevated or lowered storage position. When the storm sash is shifted upwardly Within the opening, a rail at the lower edge of the storm window panel provides a weather seal with respect to the opening by engaging the lower portion of the screen sash frame. A latch is provided on the storm window panel to hold it in its elevated position. The latch is manipulated from inside the building and is released in order to lower the storm window panel into its storage well.

Background of the invention Convertible storm and screen doors of various types have been utilized in the past utilizing either removable glass `storm panels and screen sashes or utilizing sliding storm sash and screen panels. The use of the removable storm and screen sashes presents a storage problem and, moreover, requires interchange of the storm and screen sashes as the season change. The use of self-storing storm and screen sashes is a great deal more convenient, but in the past has resulted in rather bulky structures of expensive construction.

The convertible door of the present invention has been developed to provide a relatively inexpensive, compact door structure of simplied, self-storing design which may be converted readily and which provides a weather seal when the storm window panel is shifted to its elevated active position during the winter season.

This invention relates to a combination storm and screen door, in which the door proper is fabricated from sheet metal and is adapted to be converted for use during the summer or winter seasons in a rapid convenient manner.

One of the primary objectives of the invention has been to provide a combination door of this type which includes a screen vsash and a self-storing storm sash, the arrangement being such that the door may be converted for winter or summer service simply by shifting the storm sash to an active or an inactive position without removal of either the storm sash or screen sash from the door.

` According to this aspect of the invention, the door Patented Dec. 3, 1968 proper, which is of sheet metal construction, comprises a frame having vertical and horizontal framing members, the door, having a window :opening in its upper portion, with a permanent closure panel forming its lower portion. The window opening is covered by a screen sash which is permanently attached to the door about the marginal edge portion of the opening. The storm sash is slidable vertically, such that, during the summer season, when ventilation is desired, the st orm sash is shifted to a` low ered storage position adjacent the panel which forms the lower portion of the door, leaving the screened window opening unobstructed for ventilation and insect protection. In order to convert the door for winter service, the storm sash is shifted upwardly from itsI lowered storage position to a position sealing off the screened window opening for weather protection, leaving the screen sash, which is permanently attached, in position covering the opening.

Another objective of the invention has been 'to provide a convertible storm and screen door, in which the selfstoring storm sash resides within a recess formed in the lower portion of the door when the sash is shifted to its lowered warm weather position, thereby to store the storm sash in a protected position ilush with the plane of the door.

According to this aspect of the invention, the door is delineated by vertical stiles of hollow sheet metal construction, with horizontal cross members` at the upper and lower portions of the door. The storm sash, when in its lowered self-storing position, resides within the recess or pocket formed in the lower portion of the door, the recess having substantially the same dimensions as the storm sash. The recess comprises an :inset panel which resides in a plane inwardly displaced from the common plane of the vertical door stile members and extending upwardly from the lower horizontal cross member to the lower edge of the window opening, such that the storm sash is slidable in a vertical plane from its position within the window opening forfwinter use, down- Wardly into the recess for winter storage.

In its storage position, the surface-of the storm sash is substantially Hush with the common plane of the vertical door stiles and lower horizontal cross framing member. These members provide ledges or shoulders, the lower cross member forming a horizontal ledge upon which the lower edge of the storm sash rests in its lowered position, the vertical stiles delineating vertical ledges, which include channel members facing one another and providing a slideway which extends from the recess`- upwardly to the top of the window opening in the upper portion of the door. In its preferred form, which has been selected to illustrate the principles of the invention, the storm sash resides to the outside surface of the door and it is accessible from inside the building when it is to be raised or lowered.

A further objective of the invention has been to provide a simplied latching arrangement for holding the storm sash in its elevated position, the arrangement comprising a pair of latching devices providing handle pieces accessible from 'the inside of the building for raising or lowering the storm sash and for latching it in elevated position.

Described briefly, the latching devices each comprise a bolt slidably conned within the upper portion of a channel member which forms the frame of the storm sash. Each channel member, at opposite end portions, is slotted longitudinally and each bolt includes a handle piece projecting outward through the slot and accessible from inside the building, permitting the bolt to `be shifted from a retracted position to an extended position. When extended, the end portion of the bolt interiits an aperture formed in the vertical stiles of the door frame so as to latch the storm sash in its elevated position.

In addition, each slot, through which the handle piece extends, includes an angul-ar extension formed in the channel member. The angular slots adapt each handle piece to be swung downwardly into the slot, thereby locking the bolt in its extended locking position. Accordingly to this arrangement, the handle pieces are locked in a horizontal position when the bolts are retracted so as to provide convenient handles for raising the storm sash; moreover, when the handle pieces are swung downwardly into the angular slots, they reside in a position parallel with the storm sash and are locked so that the storm sash cannot be accidentally released from its elevated position. The latching arrangement has the further advantage of utilizing the channel-shaped top framing member of the storm sash for the double function of stiffening the storm sash and of providing a slide mounting for the latching devices.

The various features and advantages of the invention will be more fully apparent to those skilled in the art from the following detailed description taken in conjunction with the drawings.

Door and frame generally Described generally with reference to FIGURES 1-4, a convertible storm and screen door constructed according to the present invention, is indicated generally at 1, and is formed of sheet metal, as explained later. The door is mounted within a door frame, indicated generally at 2, also formed of sheet metal and secured in the opening of a building wall 3.

In general, the door frame 2 comprises a vertic-al hinge jamb 4 and a strike jamb 5, with a horizontal header 6 extending across the upper ends of the jambs in the usual way. The jambs and header are provided with the usual door stops (not shown) against which the marginal edges of the door 1 are seated.

The door 1 appears in FIGURES l and 2 as viewed from outside the building, and is of composite sheet metal construction. In general, each door 1 comprises a pair of vertical Stiles 7 and 8 joined at the top portion by a horizontal cross framing member 10. The lower portion of the door includes a lower cross framing member 11 extending between the Stiles 7 and 8. The adjoining ends of the vertical stiles 7 and 8 and cross members 10 and 11 are joined to form a rigid frame for the door.

The convertible door 1 is hung within the door frame 2 by hinges 12-12 (FIGURES l and 2) having leaves secured respectively to the stile 7 and to the vertical hinge jamb 4 by means of screws (not shown). Stile 8 of the door is provided with a lock (not shown) which is operated by knobs 13 accessible from opposite sides of the door in the usual manner.

,The upper portion of the door 1 includes a screened opening 14 (FIGURES l and 5) which is closed and sealed during the winter season by a sliding storm sash 15. The opening 14 is covered by a screen sash 16 which 1s secured permanently in place over the opening. The storm sash 15 is self-storing and is shiftable from its lowered storage position (FIGURE 2) to its elevated weather protective elevated position (FIGURE l) Within the opening 14.

VThe lower portion of the door, below the opening 14, 1sl enclosed by a composite sheet metal panel, indicated generally at 17. In general, one side of the composite panel 17 (the outside of the door, in the present example) comprises a panel 18 which is depressed inwardly from the outer surface of the stiles 7 and 8 and inwardly from the lower framing member 11.

The depressed panel 18 (FIGURES 1 and 2) forms a storage recess or pocket defined by the stiles 7 and 8 and by the lower door framing member 11 to receive the storm sash 15 when it is shifted during the summer season to its lowered, self-storing position shown in FIGURE 2. The lower edge of the depressed panel 18, at the point where it joins the lower door framing member 11, provldes a horizontal ledge 20 upon which the storm sash rests when shifted to the lowered position (FIGURES 1 and 5). The inner edges of the stiles 7 and 8 delineate vertical ledges 21-21 (FIGURES 1, 2, 5 and 10) extending inwardly from the outer surface of the stiles 7 and 8 to the surface of the depressed panel 18.

Briefly therefore, the storage recess is defined by the inset or depressed panel 18, the vertical ledges 21-21 along opposite sides of the depressed panel, and the hori,

zontal ledge 20 at the edge of lower framing member 11. The storage recess is substantially equal in size to the storm sash, the arrangement being such that the storm sash is disposed approximately flush with the surface of the stiles 7 and 8 in the storage position of the storm sash.

It will be understood, at this point, that the depressed panel 18 extends upwardly from the lower horizontal ledge 20 to the lower edge of the opening 14, thus providing a passageway for the sliding storm sash 15 when it is shifted downwardly from the opening 14 into its storage position within the recess.

The construction of the sheet metal door 1 is illustrated in FIGURES 5 and 7-15. Each vertical stile 7 and 8 (FIGURE 9) comprises a generally U-shaped shell 22 formed of sheet metal comprising spaced side panels 23-23 joined by an outer connecting piece 24. The panels 23-23 delineate the opposite sides of the composite door frame and the connecting piece 24 delineates the outer edges of the door along opposite sides. The inner edge of each stile 7 and 8 consists of the inturned flanges 25--25, the inner edges of which include the lips 26-26, which are joined together by a lapped seam 27 The vertical stiles 7 and 8 and the horizontal framing members 10 and 11 each include a filler or core 28 which may be formed of wood or other material, preferably of honeycomb design (FIGURE 10). The filler 28 fits snugly between the side panels 23-23 of the Stiles and cross members to reinforce the structure and to provide a sound deadening effect. A similar core 28 is fitted between the spaced sides of the composite panel 17 (FIGURE 13) for the same purpose.

The composite panel 17 comprises the depressed panel 18 and an opposed spaced panel 30 (FIGURES 5, 10, 12 and 13). In the present example, the panel 30 is disposed to the inside of the door and the depressed panel 18 is disposed to the outside. The spaced panels 18 and 30 include inturned flanges 32 and 33 (FIGURE 10) along opposite side edges seated against the inturned flanges 25. The flanges 32 and 33 include lips 34 which lie between the lips 26-26 of the stiles 7 and 8, thus forming a part of the seam 27. One or both of the lips 34 are lapped over to crimp the seam.

The upper edge of the inner panel includes a horizontal flange 36 which is lapped over as at 37 and secured to the outer panel 18, thus forming the lower edge of opening 14 (FIGURES 5, l2 and 13). The side edges 38 of the opening are delineated by the inner edges (inturned anges 25) of the stiles 7 and 8 (FIGURES l, 2 and 9); the top edge of the opening 14 is delineated by the horizontal framing member 10.

The horizontal ledge 20, upon which the storm sash 15 rests in its lowered position, is delineated by the lower cross framing member 11 (FIGURES 1, 5 and 13). As best shown in FIGURES 5 and 13, the lower framing member 11 comprises spaced panels, one of the panels 35 (FIGURE 13) being bent inwardly to form the ledge 20 and having a flange 40 which is secured to the lower edge of the depressed panel 18.

The opposed panels 30 and 35, which form the lower framing member 11, are flush with the stiles 7 and 8 at opposite sides of the door, the panels of the framing member 11 being formed to provide a lapped seam 27 (FIGURE 14) as described earlier, to secure the ends of the framing member 11 to the stiles 7 and 8.

The lower edge of the framing member 11 includes a reinforcing channel 41 (FIGURE 15), confined between the panels 30 and 35, with its open side facing downwardly. The channel 41 is secured in place, preferably by spot welding. The upper edge of the door, which is formed by the cross framing member 10, is of similar construction. The opposite ends of the framing members 10 are joined to the stiles by lapped seams 27 and the upper edge of the door is reinforced by a channel (not shown) similar to the channel 41 shown in FIGURE 15.

Storm and screen sashes The screen sash 16 comprises a frame, indicated generally at 42, marginally embracing a screen panel 43 formed of conventional screening which may be formed of wire or of one of the commercially available fibers (FIGURES l and 2). The screen trarne 42, as detailed in FIGURES 7-9, is formed of sheet metal strips, each strip being folded upon itself, as at 44 and in pressure engagement with the marginal edge portions of the screen panel 43. The four corners of the screen frame 42 are mitered as at 45 (FIGURE 6) and the mitered joints 45 include suitable right angular reinforcement members (not shown) arranged to provide a rigid frame.

As noted earlier, the screen sash 16 is secured permanently in place over the opening 14 of the door 1. The screen frame 42 overlies the marginal porition of the opening 14 and is secured in place by a series of fastening devices 46 (FIGURES l and 2). In the present example (FIGURE 9) the fastening devices 46 comprise self-expanding rivets of a commercially available type. As shown in this View, the head of the rivet `461 seats against the screen frame 42 and the shank of the rivet passes through the frame and through the side panel 23 of the Stiles 7 and 8 of the top framing member 10. The inner end portion of the shank of each rivet, which projects inwardly through the side panel 23, is expanded as at 47 (FIGURE 9).

As best shown in FIGURES 5, 12 and 13, the lower framing member of the screen frame 42 is unattached and is spaced outwardly from the outer surface of the depressed panel 18. As ybest shown in FIGURE l2, the clearance between the depressed panel 18 and screen frame 42 provides a passageway A for shifting the storm sash 15 into the storage recess (depressed panel 18). The lower edge of the screen frame (FIGURE 12) overlaps the horizontal ange 36 of opening 14, as indicated at B. Thus, the clearance A provides a space for the lower edge portion of the storm sash 15, such that the lower edge of the storm sash seals olf the space A when the storm sash 15 is in its elevated closed position during the winter season, as indicated at C (FIGURE 12).

When the storm sash 15 is in its lowered position (FIGURE 13), the upper edge of the storm sash 15 overlaps the lower edge of the screen frame 42 as at D. Accordingly, the clearance A between 'the screen frame and depressed panel 18 is closed off by the storm sash 15 both in the raised and in the lowered positions of the storm sash.

The storm sash 15 is fabricated preferably from a plastic material such as Plexiglas, although it may be of glass, if desired. The dimensions of the plastic sash panel 15 are such that the panel (when closed) tits within the opening 141, with its lower edge portion. overhanging the lower edge 36 of opening 14, as previously indicated at C (FIGURE l2).

The storm sash is slidably mounted within the door by a pair of vertical channels 48-48 slidably embracing the marginal edge portions of the storm sash panel 15 (FIGURES 4 8). The vertical channels 48 are seated against the vertical ledges 21 which are formed by the vertical stiles 7 and 8 (inturned anges 25).

A horizontal channel 50, similar to the vertical channels 48, extends across the top of the opening 14 (FIG- URES 3, 7 and 8) and is arranged to receive the upper edge portion of the storm sash 15 in its elevated position. The adjoining ends of the Vertical channels 48 and horizontal channel 50 are mitered as at 51 (FIGURES 5 and 6).

It will be understood, at this point, that the Vertical channels 48 extend continuously along the sides of the opening 14 and also along the sides of the depressed panel 18, as delineated by the Stiles 7 and 8 of the door frame, so as to guide the storm sash 15 in its sliding motion from the elevated to the lowered position. The

vertical channels `48 and the horizontal channel 50 may be secured to the inturned flanges 25 of the stiles 7 and 8 and to the horizontal framing member 10 by rivets 446 (not shown) or the channels may be spot welded in place.

The lower edge portion of storm sash 15 is provided with a stop rail 52, formed of sheet metal and having a channel section 53 and a flange 54, which is secured to the storm sash by the rivets 55 (FIGURES 2, 5 and 12). The upper edge portion of the storm sash 15 includes an upper stop rail 56, also comprising a channel section 57 and an attaching ange 58 (FIGURES 3, and 5-8). The upper edge portion of the storm sash opposite the upper stop rail 56 includes a reinforcing plate 60 in registry with the upper stop 56 (FIGURES 5, 7 and 8).

The upper and lower stop rails 52 and 56, reinforce the storm sash panel 15 along its upper and lower edges; the opposite ends of both stop rails terminate inwardly from the marginal edges of the storm sash panel as at 61 (FIG- URES and 6), leaving the marginal edges free' to be slidably engaged in the vertical slide channels 48. The upper stop rail 56 is spaced downwardly from the upper edge of the storm sash panel as at 62 (FIGURES 6-8), leaving the upper marginal edge portion free to intert the horizontal channel 50 at the upper end of the opening 14.

In its lowered position, the lower edge of the storm sash rests upon the ledge 20, as explained earlier (FIGURES 2 and 13). In order to hold the storm sash 15 in its closed, elevated position during the winter season, the upper edge portion of the storm sash 15, along its opposite side edges, include respective slidable latches, indicated generally at 63 (FIGURES 3, and 5-8).

Each latch 63 comprises a cylindrical bolt 64 slidably confined within the channel section 57 at opposite ends. t

The channel section 57 includes a longitudinal slot 65, formed in its web portion at opposite ends. A handle piece 66, which extends at right angles to the bolt 64, interfits the longitudinal slot 65. The handle piece 66 permits the bolt 64 to be shifted from the retracted position, shown in broken lines as at 67 in FIGURE 6 to the extended latching position shown in dotted lines at 68 in this view.

In its unlatching position 67, the outer or latching position of bolt 64 is retracted from the marginal side edge of the storm sash panel 15. In its extended or latching position 68, the outer end portion of the bolt projects through an aperture 70 (FIGURE 8) which is formed in one of the inturned `flanges of the stiles 7 and 8. It will be understood that the latches 63 are in duplicate along opposite sides of the storm sash 15, the stiles 7 and 8 both being provided with apertures 70 to receive the end portion of the bolts 64.

In the locking position of the latches 63 (FIGURES 6 and 7) the handle piece 66 of each latch is turned to a downward position and into engagement with a lateral slot 71 (FIGURES 5 and 6) which is formed in one of the limbs of the channel section 57. The lateral Slots 71 open into the longitudinal slots 65.

When it is desired to lower the storm sash 15 from the closed position shown in FIGURES 3 and 6e8, the handle pieces 66 of the two latches are raised from the vertical locking position of FIGURE 6 to the horizontal position of FIGURE 8, then the bolts are withdrawn by shifting the handle pieces 66 inwardly along the longitudinal slots 65 toward one another, thus retracting the bolts 64. With the handle pieces confined in the longitudinal slot 65, they are locked in the horizontal position (FIGURE 8) thus providing handles conveniently accessible from inside the building for manipulating the storm sash 15.

When in the fully lowered position (FIGURE 13), the handle pieces 66 remain latched in their horizontal position and reside slightly above the horizontal ledge 36 which delineates the lower edge of the opening 14 (FIG- URE 13) for convenience in gripping the handle pieces when the sash is to be raised.
